摘　　要：海表温(SST)是影响渔场的重要环境因子。根据2008年我国冰鲜金枪鱼延绳钓船在瓦努阿图周边海域的生产统计数据,结合卫星遥感获得的SST资料,分析了长鳍金枪鱼各月渔场时空分布及其与SST的关系。K-S检验表明,长鳍金枪鱼渔场形成与SST关系密切。The sea surface temperature（SST） is an important environmental factor affecting fishing ground.According to the catch data from Chinese tuna longlining fleets and SST from satellite remote sensing in the waters around Vanuatu in 2008,the spatial and temporal distribution of albacore tuna and its relationship with SST were carried out.The result shows that the fishing grounds are distributed in the 12°S-14°S and 172°E-175°E,and the suitable SST ranged from 29 to 30℃ during January to April.During May to June,the fishing grounds are located in the waters of 10°S-15°S and 174°E-175°E,and the suitable SST is 28-29 ℃.In July the production was highest in the whole year,the fishing grounds are distributed in the areas of 10°S-15°S,170°E-175°E and 23°S-24°S,175°E-177°E,its suitable SST are 27-29 ℃and 23-24 ℃ respectively.During August to September,the monthly fishing grounds are distributed in the areas of 24°S-26°S and 174°E-176°E,13°S-16°S and 173°E-175°E respectively,the monthly suitable SSTs are 21-23 ℃ and 27-28 ℃ respcetively.In October the fishing ground is distributed in the waters of 12°S-17°S,173°E-176°E and 14°S-15°S,159°E-161°E,and its suitable SST is 27-29 ℃.During November to December,the monthly fishing grounds are located in the areas of 16°S-19°S and 171°E-174°E,19°S-22°S and 173°E-175°E,their monthly suitable SSTs are 28-29 ℃.The K-S test indicated that the formation of fishing grounds is closely related with SST.
